If the Thymus gland shrank, and stopped producing thymosin, what would happen is that we would loose a few of our "T" cells, which are detrimental to the immune system.

(A). Energy is lost when machines don't work right.
Explanation:
The false statement from the choices is that energy is lost when machines do not work right.

- Energy is transformed from one form to another validates the fourth choice. We can covert from thermal to mechanical energy and vice versa.
The only odd choice is that energy is lost when a machine doesn't work right.
